FIG. 1 illustrates an example breathing assistance apparatus 20 that provides a humidified and heated flow of fluid to a user or patient 10. The illustrated apparatus 20 comprises a high-flow breathing assistance apparatus; however, features, aspects, and advantages of some embodiments can be used with other types of apparatus used to supply a humidified and/or heated flow of fluid (e.g., gases or air) to the user or patient 10. For example, features, aspects, and advantages of some embodiments can be used with CPAP machines, insufflation humidifiers for laparoscopic or other surgical procedures, respiratory humidifiers, humidifiers for noninvasive ventilation applications, humidifiers for invasive ventilation applications, infant resuscitation devices, and the like. Embodiments described herein can be used with the breathing assistance apparatus and display interface described in international PCT patent application publication WO2013/151448, which is incorporated by reference in its entirety so as to form a part of this specification.

In some embodiments, the apparatus 20 can include a display 40 configured to display a series of images in succession that illustrate an animation and/or scrolling text. The animation and/or scrolling text can be used to instruct a user on how to perform a particular action, to provide information regarding the apparatus 20 to the user, or to provide an indication of an operational mode of the apparatus 20 to the user. The series of images can be displayed in response to a triggering event and the animated action can be configured to present one or more methods of responding to the triggering event. The apparatus 20 can be configured to detect various triggering events and to automatically display a corresponding series of images. For example, the apparatus 20 can be configured to detect a fault condition. In response, the apparatus 20 can display a scrolling text instructing the user how to correct the fault condition.

In some embodiments, the series of images displayed on the display 40 can include flashing lights, coloring, shading, or other similar visual cues to correlate the animation or scrolling text to relevant information displayed on the display 40. For example, the scrolling text can have a colored background that is the same or nearly the same as an icon on the display or other information on the display to which the scrolling text applies. In some embodiments, no words are used such that the visual images can communicate an operational mode, fault condition, or the like to any user independent of language or technical background. In some embodiments, audible cues or instructions can be provided in addition to the animations and/or scrolling text.

With continued reference to FIG. 1, the apparatus 20 comprises a flow generating apparatus 22. The illustrated flow generating apparatus 22 can be connected to a patient interface 24 with a flexible conduit 26. The patient interface 24 can be any suitable patient interface. For example, but without limitation, the patient interface 24 can comprise noninvasive interfaces including, but not limited to, adult nasal cannula, infant nasal cannula, full face masks, combination oral/nasal masks, nasal masks, nasal pillows, high flow cannula, or the like. In some configurations, the patient interface 24 can comprise invasive or minimally invasive interfaces including, but not limited to, endotracheal tubes, insufflation devices, or the like. In some configurations, adaptors and connectors can be provided for coupling to tracheotomy devices and masks.

In the illustrated configuration, the flexible conduit 26 can comprise a heating element 30 and a sensing element 32. In some configurations, the sensing element 32 can be positioned at an end portion of the flexible conduit 26 closest to the patient interface 24. In some configurations, the sensing element 32 is positioned within the lumen defined by the flexible conduit 26 such that the sensing element 32 is exposed to the fluid being carried within the lumen. The sensing element 32 can sense a characteristic or attribute of the fluid being carried within the lumen. In some configurations, the sensing element 32 is arranged and configured to sense the temperature of the fluid passing through the lumen.

The end of the flexible conduit 26 closest to the flow generating apparatus 22 comprises a connector 34. The connector 34 can be configured to establish both a pneumatic connection between the flow generating apparatus 22 and the lumen of the flexible conduit 26 and an electrical connection between at least the heating element 30 of the flexible conduit 26 and the flow generating apparatus 22. In some configurations, the connector 34 facilitates establishing both the pneumatic connection and the electrical connection in a single step.

With continued reference to FIG. 1, the flow generating apparatus 22 comprises a user control interface 36. The user control interface 36 enables interaction between the user, patient 10, or another person (e.g., without limitation, health professionals, distributors, or the like) and the flow generating apparatus 22. The illustrated user control interface 36 comprises a display screen 40. The display screen 40 can be any suitable display screen. In some configurations, the display screen 40 comprises an organic light-emitting diode (OLED) screen. In some configurations, the display screen 40 can comprise a full color display with a pixel count of between about 6,000 pixels and about 500,000 pixels. In some configurations, the display screen 40 can comprise a pixel count of about 20,480 pixels. In some configurations, the display screen can comprise a screen size of about 128 pixels by about 160 pixels (vertical by horizontal). In some configurations, the display screen can be about 1.8 inches diagonally to about 4 inches diagonally. To reduce heat transferred from the screen to other components of the apparatus 22, the screen can be run with a black screen (e.g., most of the pixels are inactive during operation of the apparatus 22).

The illustrated user interface 36 comprises a power key/button 42, a mute key/button 44, an up arrow key/button 46, a down arrow key/button 50 and a mode key/button 52. In some configurations, the user interface 36 can include some combination of mechanical keys, electro-mechanical keys, and touch-sensitive capabilities such as where the display 40 comprises a touch-screen and navigation through a menu structure or other suitable manner of device operation can be provided via the display 40.

The apparatus 22 also comprises a suitable controller, which includes memory and other components used for sensing various characteristics of flows and operation of the apparatus. Moreover, the apparatus 22 can comprise a speaker or other audible alert generator.

Example User Interface Animations

FIG. 2 illustrates an example of a series of images used in an animation showing a breathing apparatus display operating in a transport mode. The breathing apparatus display can include a display 200 that provides information relevant to the operation of the breathing assistance apparatus. A portion of the display 200 can be used to provide an animation. For example, FIG. 2 illustrates a sequence of images that shows an animated cart 205 a, 205 b, 205 c, moving across a portion of the screen. When shown in succession, it appears as though the cart is moving. In addition, a timer is displayed in the animation region. The animation can be configured to convey to a user that the apparatus 22 is being operated in a transport mode. This can be done, as shown, using a moving element associated with the apparatus, such as the rolling cart. In some embodiments, other animations can be used which convey to a user that the apparatus is in a transport mode such as, for example, a car, traffic signals, a dynamic arrow, flashing indicator, or the like. In some embodiments, scrolling text can be used to indicate that the apparatus is in a transport mode.

The breathing assistance apparatus can be used in a transport mode. For example, in the transport mode the output gas temperature setting can be reduced (e.g., typically to about 31 C from about 37 C in the normal mode). In some embodiments, entering the transport mode can cause the apparatus 22 to reduce or minimize power usage by the heater plate, motors, and the like. The reduction or minimization of power can be done to reduce power consumption when connected to a universal power supply (“UPS”) for transportation from one location to another when the apparatus cannot or will not be plugged into an electrical socket. When in transport mode, the apparatus 22 can have a countdown timer with a preset period of time (e.g., about 30 minutes), after the expiration of which the apparatus 22 automatically reverts to a normal mode of operation. The screen can display the temperature setting and the countdown timer indicating when the apparatus will automatically revert to a normal mode of operation. In some embodiments, the countdown timer can be reset by the user if the transportation will last longer than the timer provides. In some embodiments, the apparatus reverts to the mode of operation it was in prior to being put into the transportation mode. In some embodiments, the transportation mode screen can display other information or indicators, such as a flow rate, an oxygen setting, a youth-sub mode, or the like.

In some embodiments, the apparatus 22 can be configured to enter transport mode when connected to a UPS. The apparatus 22 can be configured to understand and communicate appropriate handshake protocols with UPS systems so as to recognize when it is connected to a UPS rather than an electrical wall socket. In some embodiments, the apparatus 22 can remain in transport mode until disconnected from the UPS and/or connected to an electrical wall socket.

The display 200 can be configured to change only a portion of the screen while maintaining another portion unchanged. For example, the animations can change when the apparatus detects a triggering event, such as the end of a transport mode of operation. When the animation changes, the static information can remain unchanged and/or unaffected by the change to the animations.

FIG. 3 illustrates an example of a series of images used in an animation showing a breathing apparatus display providing instructions to a user as scrolling text across the display in conjunction with static information. The breathing apparatus display can include a display 300 that provides information relevant to the operation of the breathing assistance apparatus. A portion of the display 300 can be used to provide scrolling text. For example, FIG. 3 illustrates a sequence of images that shows scrolling text 305 a, 305 b, 305 c, moving across a bottom portion of the screen. When shown in succession, it appears as though the text is moving or scrolling across a portion of the screen. The text of the scrolling text can be surrounded by a colored region, or a banner. The colors of the text and banner can be different and can have a high contrast to facilitate reading. In addition, static information is displayed on the display 300, including icons, oxygen saturation value readings, oxygen saturation ranges, or the like. The scrolling text can be configured to convey instructions to a user, including to “Monitor patient O₂ saturation,” as illustrated. The scrolling text can include a background color or a font color that is the same or similar to the general color of the information being presented (e.g., the oxygen saturation value), the background or foreground of an icon (e.g., the “O₂” icon), or other such information presented on the display 300. Other icons, measurements, ranges, and the like can be used in the display 300, such as flow rate readings, timers, operational mode indicators, menus, and the like. In some embodiments, the scrolling text can include flashing colors or text to indicate an urgent message or an alarm. In some embodiments, an audible cue can be played with the scrolling text and/or audible instructions can be provided which correspond to the scrolling text. For example, a melody or chime can be played in conjunction with an animation or scrolling text associated with a warning. Audible cues can be different for different animations and/or scrolling text messages.

The static information in FIG. 3 can be static relative to the dynamic information being presented as scrolling text or animations. The static information can be configured to change according to readings or values measured by the apparatus, or other events. In some embodiments, the display 300 can change according to user input, triggering events, and the like. The display 300 can be configured to change only a portion of the screen while maintaining another portion unchanged. For example, the scrolling text can change when the apparatus detects a triggering event. When the scrolling text changes, the static information can remain unchanged and/or unaffected by the change to the scrolling text. Similarly, the scrolling text can continue to present the same text information when the display 300 changes what is being displayed, such as changing from an oxygen saturation reading to a flow rate reading. As another example, when the display interface provides a menu to the user, the scrolling text can remain scrolling across the bottom of the page or the menu can occupy the entire display 300.

FIG. 4 illustrates an example of a series of images used in an animation showing a breathing apparatus display providing information to a user as scrolling text across the display in conjunction with dynamic information and other animations. The breathing apparatus display can include a display 400 that provides information relevant to the operation of the breathing assistance apparatus. A portion of the display 400 can be used to provide scrolling text. For example, FIG. 4 illustrates a sequence of images that shows scrolling text 405 a, 405 b, 405 c, moving across a bottom portion of the screen. When shown in succession, it appears as though the text is moving or scrolling across a portion of the screen. In addition, other dynamic information and animations are displayed on the display 400, including a timer and an animated fan. The scrolling text can be configured to convey instructions to a user that are related to the animated information being displayed, including to “Do not wear interface during . . . ,” as illustrated. The scrolling text can include a background color or a font color that is the same or similar to the general color of the information being presented (e.g., the fan and timer), or other such information presented on the display 400. In some embodiments, the scrolling text can include flashing colors or text to indicate an urgent message or an alarm. In some embodiments, an audible cue can be played with the scrolling text and/or audible instructions can be provided which correspond to the scrolling text.

The animations in FIG. 4 can be configured to change without affecting the scrolling text in the display 400. The animations can be configured to change according to readings or values measured by the apparatus, changes in operational modes, or other events. In some embodiments, the display 400 can change according to user input, triggering events, and the like. The display 400 can be configured to change only a portion of the screen while maintaining another portion unchanged. For example, the scrolling text can change when the apparatus detects a triggering event. When the scrolling text changes, the animations can remain unchanged and/or unaffected by the change to the scrolling text. Similarly, the scrolling text can continue to present the same text information when the display 400 changes the animations being displayed, such as changing from transport mode to normal operation. As another example, when the display interface provides a menu to the user, the scrolling text can remain scrolling across the bottom of the page or the menu can occupy the entire display 400.

In the displays 300 and 400 of FIGS. 3 and 4, respectively, scrolling text can provide warnings, instructions, operational parameters, preventive warning information, fault conditions, and the like to a user. Examples of such information can include, without limitation, replacing a filter of the apparatus, detecting a disconnection from the conduit heater wire, detecting a loss of resistance to flow, indicating a possible leak, connection of the youth sub-mode cannula, detecting a higher than expected resistance to flow, unkinking a hose, determining if the youth sub-mode interface is installed, unclogging a nasal cannula, detecting oxygen content above or below a set level, detecting a water level to be low or empty, detecting an oxygen supply during a disinfection mode, detecting an interruption in the oxygen supply, detecting a prolonged stoppage of user breathing, detecting a user breathing rate that exceeds a limit, and the like. Thus, in some configurations, the apparatus 22 is configured to prompt users to perform maintenance tasks and troubleshooting through the use of animations, scrolling text, or other graphical displays.

Preferably, the apparatus 22 is capable of displaying the scrolling text in any of a plurality of languages, which can be set by the user. In some embodiments, the scrolling text can be presented in multiple languages in succession. For example, the scrolling message can be displayed first in English, then in Spanish, then in French, or any other language and in any order. This can be advantageous in that it reduces or eliminates the need for creating or providing a user manual in multiple languages.

In some embodiments, the letters of the scrolling text can be the same color as the background of the display screen or display interface. In some embodiments, the banner around the scrolling text can be the same color as the background of the display screen or display interface. The text can be a bright color to contrast with the background and/or banner. Similarly, in some embodiments the banner can be a bright color to contrast with the background and/or text.

In some embodiments, the scrolling message can be shown for a limited duration. The limited duration can be based on an amount of time being displayed or a number of times the full message is displayed on the display interface. For example, the scrolling message can be configured to be displayed 3 times. Other numbers can be used as well, including 1 time, 2 times, 4 times, 5 times, 6 times, etc. As another example, the scrolling message can be configured to be displayed for 5 seconds, 10 seconds, 30 seconds, 1 minute, 2 minutes, etc.
